WinRAR (WINZIP) compression and decompression implementation (C # window platform)

The principle of this article is to use the Windows platform-installed WinRAR (WinZip) to implement calls to C # programs (Note: WinRAR compression decompression WinZip is also applicable).

Let's take a look at the support invocation command of WinRAR (WINZIP) itself:

Compression command: a {0} {1}-r "{0}: File name after compression | {1}: File physical path to be compressed "

Ex: "A Your sister. rar f:\\mm-r" (meaning to compress the folder of MM under F disk to "your sister. rar" file)

Extract command: x {0} {1}-y "{0}: File name to Unzip | {1}: Physical path of the file to be extracted "

Ex: "X-sister. rar f:\\-y" (The physical path of the file to be compressed: "F:\\-yao sister. rar")

Parameter description

Parameters	Meaning
A	Adding files to a compressed package
X	Extracting compression from a compressed package with a full path

Winrarcsharp win = new Winrarcsharp (); win. RAR ("f:\\aaa\\", "f:\\", "A.rar");//Compression (compressing "f:\\aaa\\" directory Files to "F:\\a.rar") win. UnRAR ("F:\\ Yo M.zip", "f:\\mm", "GG"); Unzip (extract "F:\\ Yo m.zip" to "F:\\mm\\gg" directory)
